Chang’e‑7’s delayed south-pole mission combines orbital mapping with a mini-flying probe designed to sample permanent shadow near Shackleton and measure water and its isotopes.
Starlab's three-level ground mockup is taking shape inside Building 9, turning NASA's planned shift from an agency-owned ISS to commercially operated stations into a human-scale test.
Across 13 integrated tests, Starship moved from breaking its own launch pad to guiding an intact upper stage into a distant ocean landing zone.
The striking percentages came from a 2020 nonlinear model, not a Mars crew. Its input data predated current resistance exercise and stopped at 228 days, far short of the 1,000-to-1,200-day profile it projected.
B1067's 36 flights show how Block 5 moved beyond its original ten-flight maintenance goal, but comparing the first stage with Discovery requires care about what each vehicle did.
Artemis II's first four-mile rollout took nearly 12 hours at no more than 0.82 mph. Orion later met Earth's atmosphere near 25,000 mph before its heat shield and parachutes slowed the crew for splashdown.
Voyager 2's saved watts preserve magnetic-field, plasma-wave and cosmic-ray measurements from beyond the heliopause, where no approved replacement mission is yet on its way.
SpaceX has already caught a Super Heavy booster. Catching the re-entering Starship upper stage would test whether its legless design can become a practical reuse system.
What separates those who reach the stars from those who give up after rejection—and what can it teach the rest of us about resilience.
When the final bill came due, it wasn't Mir's age or achievements that doomed the space station—it was simply too expensive to keep alive.
The onboard software was correct. A ground-file interface undercounted repeated thruster impulses by a factor of 4.45, while warnings and safeguards failed around it.
After 24 days at sea, recovery crews guided the first intact Starship upper stage to calmer water off Christmas Island, preserving an unprecedented post-flight test article.
Blue Origin stopped New Shepard despite a busy 2025, while Virgin Galactic sold a limited new batch of reservations for a Delta spacecraft that still has to complete its test programme.
MMX will use a rover, two sampling systems and a brief Phobos landing to return more than 10 grams of material to Australia in 2031.
A fighter pilot's discipline became essential when Krikalev found himself stranded in orbit as the Soviet Union collapsed around him.
LRO thermal data and UCLA-led modelling show why permanent shade in certain lunar pits can remain near 17°C, while cave habitability still depends on access, structure, air and power.
